The ideal truss shown is supported by a pinned connection

at point D and a roller connection at point C.

Loads are applied at points A and F.

Given:  P2 = 8000 N  All dimensions are in meters 

2. If P1 = 1800 N, what is the the force in member CE

3. If the force in member DE = 3000 N, what must 

be the applied load P, for equilibrium? 

Situation 2. A bin holds a cylinder as shown. Each cylinder weighs "W" and has a diameter of 600 mm. The width of the bin is 0.9m. Neglect friction. 

1. Which of the following gives the surface reaction 

at F when W = 900 N?

Situation 2. A bin holds a cylinder as shown. Each cylinder weighs "W" and has a diameter of 600 mm. The width of the bin is 0.9m. Neglect friction. 

2. Which of the following gives the wall reaction at point C when W = 900 N?

Situation 2. A bin holds a cylinder as shown. Each cylinder weighs "W" and has a diameter of 600 mm. The width of the bin is 0.9m. Neglect friction. 

3. If the wall reaction at E is 2000 N, determine the weight, W, of the cylinder.

Situation 3. Classify each of the structures shown in the as externally unstable, statically determinate, or statically indeterminate. If the structure is statically indeterminate externally, then determine the degree of external indeterminacy.

Classify Figure A.
